What is the relationship between the amount of effort and distance needed to lift a load when using different types of pulleys?

Yes, it does, but it is only a second order effect.
In other words, it is so small an effect that you can almost always neglect it. What is significant is the number of pulleys in use. After a certain number of pulleys there is no advantage to adding more.

How can you increase a pulleys mechanical advantage?
By increasing the effort distance on the machine.
How is a lever different from a machine made with ropes and pulleys?
Both pulleys and levers are mechanical devices designed to gain an advantage over an inert load force and both are simple machines. The main difference with a pulley system is the direction of force, and the effect can be different.
What is the difference between a stationary pulley and a mobile pulley?
Very simple the answers in your own question.Stationary pulleys works on its own axle of rotation while the Movable pulleys move with Load like the one in cranes.

What is the disadvantage of adding more pulleys to a system of pulleys?
There are two disadvantages:You will have to pull the rope a long distance to move the load a relatively short distance.There will be more loss of energy to friction with more pulleys.

How does pulleys work?
Pulleys can multiply the force you apply. Example: I pull down on a pulley with TWO Pulleys THREE supporting Strands and the force is Multiplied by a factor of TWO, but you have to pull TWICE the length of Rope as the Distance the Object is Raised. Therefore you can LIFT more WEIGHT than you normally could.The relationship of Supporting Strands to the Force Multiplier is:(the number of Supporting Strands) - 1So a Pulley system with 5 Supporting Strands with Multiply YOUR input Force by 4 times. This type of System is referred to as "Block and Tackle".
Where is the tension pulley on 2006 Ford Focus?
Somewhere between the other pulleys.
How does a pulley change the input force?
A single pulley only changes the direction of the applied force. A second or more pulleys on the same rope will multiply the force applied by decreasing the distance of the applied force. This arrangement is called a block and tackle. Two pulleys double the force and halve the distance the force acts upon the mass. Three will triple the force while reducing the distance by 1/3, and so on. If 1 pound of force is applied to a rope with four pulleys on it over the distance of 10 feet of rope it will raise a 4 pound weight 2 1/2 feet.
